Title: Purification of effluent by treatment with - a flotation agent
IPC: C02F3/12
Filed: 1969-12-24
Abstract: The purification of effluent particularly from paper-making, is effected by the addition to the raw water, before or after removing large impurities, of a floatable flotation agent with the property of adsorptively binding organic material in solution or colloidal dispersion, and more especially by the addition of a biologically active organic sludge and/or inorganic materials such as iron, calcium or aluminium hydroxide flocculants. The process may be carried out in several stages in series connected flotation tanks with fresh addition of the flotation agent in each stage, at least a part of the solid produced being transferred from one tank to the next.

Title: Double grooved boat for semiconductor compound mfr. - by vapour liquid reaction, giving improved yield
Inventor: JACOB GUY
IPC: C30B11/12
Filed: 1973-07-05
Abstract: Method of growing a semiconductor compound esp. GaP. in the form of an ingot comprises a reaction synthesis in a sealed chamber by reacting a first volatile component having a vapour pressure at least equal to the dissociation pressure of the cpd., with a second component in the liquid phase in a elongated boat in horizontal position. The closed chamber is heated by radiant heat. The excess of liquid component appearing during the course of the reaction, representing the excess of liquid over the amount of cpd. obtd. is removed continuously during the course of the reaction. The height of the ingot as it grows in the boat remains constant unlike in prior art methods, hence the profile of the temperature gradient does not change during the reaction and the yield is improved.

Patent FR-2201542-A1 (FR)
IPC: H01L23/15
Filed: 1973-10-02
Abstract: A metalization process for the manufacture of hybrid integrated circuit elements including boards and semiconductors to be attached thereto involves applying to a substrate of insulating material such as aluminum oxide, successive layers of sputtered nickel-chromium and nickel, an electroless deposit of nickel-boron and, frequently, an electro-deposited layer of gold. The assembly is then normally heat-treated to stabilize the resistive layer. The addition of the nickel-boron layer provides many advantages in that reliable low-temperature solder connections may be made to it, ultrasonic wire bonds of high reliability may be accomplished with the usual aluminum wire supplied with most discrete components, the heat-treating step is considerably shortened in time with greater stability of resistance values, and the assemblies thus manufactured are capable of operating in comparatively high-temperature environments. The same metalization process applied to semiconductors renders them easily solderable and avoids using high temperature eutectic bonding with the accompanying exposure of the semiconductors to elevated temperatures, often for prolonged periods. As a result, circuit assemblies thus manufactured are readily repairable, in most instances, since no high-temperature bonds are required.

Title: Embossed thermoplastic films with high mechanical strength - produced by indirect heating and immediately passing over cooled embossing roller
IPC: B29C43/00
Filed: 1974-01-04
Abstract: The film is first heated to above its softening point by e.g. radiation, convenction or forced air draught, without direct contact with the heat source. It then moves immediately between two cooled metal pressure rollers, of which one bears the embossing pattern while the other has a resilient coating to act as cushion. The film passes through 90 degrees on the embossed roller to a secondary cooling roller, there passes again through 90 degrees and is finally reeled or fed direct to further processing.

Title: Line state detector and coder in telephone systems - is performed using comparators connected to lines and earth
Inventor: PRUDHON LUCIEN PIERRE EMILE
IPC: H04M3/36
Filed: 1974-01-11
Abstract: Detection and coding of the states of telephone lines is employed in traffic observation equipment to measure traffic floe. Detection is performed using comparators connected to the lines and earth and permits its connection to autocummutators without immersion of battery polarity. A number of telephone lines are connected to an autocommutator and lead to several locations. Resistors are connected to each line and to the autocommutator earth. electrical signals in the lines are sensed and the three output signals are directed towards multiplexers followed by impedance matching circuits for amplification and detection and coding. The multiplexers enable the state of any line to be detected in a random or cyclic manner.

Title: Nucleic acids extraction from yeast - using improved acid hydrolysis process
IPC: C07H21/02
Filed: 1975-03-27
Abstract: Nucleic acids are extd. from yeasts intended for human consumption by acid hydrolysis, the improvement comprising using a cells/HCl soln. ratio of about 1:1. The process consists in introducing the unpressed, hydrocarbon-washed moist yeast cell paste into a vessel, injecting steam at the vessel base, extruding with stirring, via the base, the fluidised paste into an acidification chamber, stirring being effected with a helical stirrer, injecting the HCl soln. pref. at a concn. of 0.15N-1N into the acidification chamber and kneading the paste with twin helical stirrers dispersed axially vertically relative to the first helical stirrer, extruding the paste into an incubation chamber kept at 100 degrees C extruding into a washing tank, recovering the hydrolysed cellular paste and weighing and finally recovering the washing soln. and hydrolysate concentrate. The process ensures complete hydrolysis of the nucleii acids which if present in the yeast for eventual consumption would give rise to formation of uric acid.
